In my opinion, it is up to the site owner to verify to legal standards, exactly who is uploading any content. Youtube is turning a blind eye to this ambiguity, profiting from it and should be held responsible. If they can't, or are unwilling to do this, then either they should pay royalties and punitive damages as directed or cease operations.
It is my understanding that the reason we have copyright laws and statutes in the first place is for the originator of creative works to ensure and maintain their right to control and profit from their work.
